FIG. 2 depicts a partial cross section viewof a packing box according to one or more embodiments described. FIG. 3depicts a schematic view of a packing box prior to assembly according toone or more embodiments described. Referring to FIGS. 1, 2, and 3, thepacking box can be formed from a single paperboard. The singlepaperboard 100 (identified in FIG. 3) can include portions for: outersides 1, 2, 3, 4, and 5; interior sides 6 and 7; interior bottoms 8, 9,10, and 12; an interior top 11; an outer bottom 13; an outer top 14, airvents 30, 31, and 33; narrow slots 35, 36, 37, 38, 39, 40, 41, and 42;and plugs 26, 34, 50, 51, 52, 53, 54, and 55. As described in moredetail below, the paper board 100 can be folded along one or more ofthese portions to provide an assembled box 105 (depicted in FIG. 1).

Referring to FIG. 3, narrow slots 35, 36, 37, 38, 39, 40, 41, and 42 canbe disposed or formed on the outer side paperboards 1, 2, 3, 4, and 5,interior bottom paperboards 8 and 9, and/or air vent 31, respectively.Plugs 26, 34, 50, 51, 52, 53, 54, and 55 can be formed on the outer side5, interior side 6, interior bottoms 10 and 12, interior top 11, outerbottom 13, and outer top 14, respectively.

The outer side 5, air vents 31, 33, and plug 34 can be arrangedperpendicular to outer top 14 and set inside outer sides 2, 3. Plug 26can be connected through narrow slot 38 and plug 50 can be connectedthrough narrow slot 41. Interior bottoms 8, 9, 10, and 12 can beperpendicular to outer sides 1 and 3 and set inside outer bottom 13.Interior side 6 can be perpendicular to outer bottom 13 and set insideouter side 3. Plug 51 can be connected through narrow slots 39 and 40.Interior side 7 can be perpendicular to interior bottom 10 and can beset inside outer side 1. Interior top 11 can be perpendicular tointerior side 7 and can be set inside outer top 14. Plug 55 can beconnected through narrow slot 42.

In assembly, the packing box 105 can be formed by folding theaforementioned portions of the paperboard 100. In one or moreembodiments, the outer side 2 can be folded to be perpendicular to outerside 1. Outer side 5 can be folded to be perpendicular to outer side 4.Outer side 4 can be folded to be perpendicular to outer side 3. Outerside 3 can be folded to be perpendicular to outer side 1. When outerside 5 is overlaid on outer side 2 on the inside, plug 26 can connect tonarrow slot 38, and plug 50 can connect to narrow slot 71. Accordingly,outer bottom 13 can be folded to be perpendicular to outer side 4 andplug 54 can connect to narrow slot 37. Interior bottom 12 can be foldedto be perpendicular to outer side 3 and outer side 1 and can be overlaidon outer bottom 13 on the inside. Interior bottom 9 can be folded to beperpendicular to outer side 1 and can be overlaid on interior bottom 12on the outside. Interior bottom 8 can be folded to be perpendicular toouter side 2 and outer side 1 and can be overlaid on interior bottom 12on the inside. Interior side 6 can be folded to be perpendicular tointerior bottom 8 and outer side 1 and can be overlaid on interiorbottom 12 on the inside. Outer side 6 can be folded to be perpendicularto interior bottom 8 and outer side 1 and can be overlaid on outer side3 on the inside. Plug 51 can connect to narrow slots 39 and 44. Interiorbottom 10 can be folded to be perpendicular to outer side 4 and can beoverlaid on interior bottom 8 on the outside. Plug 52 can connect tonarrow slots 35 and 36. Interior side 7 can be folded to beperpendicular to interior bottom 10 and can be overlaid on outer side 1on the inside. Air vent 31 can be folded to be perpendicular to outertop 14. Outer top 14 can be folded to be perpendicular to outer side 1.Plug 34 can be folded to be perpendicular to outer top 14 and can beoverlaid on outer side 4 on the inside. Interior top 11 can be folded tobe perpendicular to interior side 7 and can be overlaid on outer top 14on the inside. Plug 55 can connect to narrow slot 42.

As used herein, the term “perpendicular” refers to the relativeorientation between two or more portions of the packing box 105, and isnot limited to a 90° angle therebetween so long as the two or moreportions can be arranged and interlocked to form a box. Accordingly,“perpendicular” includes a substantially perpendicular arrangement ororientation and includes any angle between 60° to 120°, preferably 70°to 110°, more preferably 80° to 100°, and more preferably 85° to 95°.
